I don't normally do reviews but felt compelled to do this one.

I contacted David about a supposed gas leak in the oven at a rental. The emergency plumber had been out to to identify and isolate the leak. David always returned my calls when he couldn't answer. He arrives at the allotted time. Found that the oven hadn't been isolated and did not have a leak.

David travelled to Hoppers Crossing, spent 20 minutes checking and running the oven only to find no problem.
Two weeks later, I contacted him for some feed back and to chase the invoice. His response was there was no problem so no invoice. I cannot recommend DBHL highly enough. Still amazed at the timely service and generous attitude.
DON'T WASTE YOUR TIME WITH ANYONE ELSE
